Impact of Supply Chain Integration on Manufacturing Firm Performance in the Fast-Moving Consumer Goods Sector in Nigeria

This study examines the impact of supply chain integration on manufacturing performance outcomes in fast-moving consumer goods firms operating in Nigeria, filling a research gap in supply chain management literature focused on sub-Saharan African manufacturing contexts. Supply chain integration, encompassing internal integration, customer integration, and supplier integration dimensions, is hypothesised as a significant predictor of manufacturing performance in the competitive Nigerian FMCG market where supply chain disruptions remain frequent. This research employs a positivist survey research design, collecting data from one hundred and forty-two manufacturing managers in FMCG companies across Lagos, Ogun, Rivers, and Kano states. Supply chain integration constructs are measured using validated multi-item scales adapted from the literature and assessed for reliability and validity through structural equation modelling. Manufacturing performance is operationalised across quality, cost, flexibility, delivery, and innovation dimensions. Results confirm that all three integration dimensions positively and significantly predict manufacturing performance, with internal integration demonstrating the strongest direct effect. Customer integration shows the largest indirect effect through its influence on innovation performance. Moderation analysis reveals that information technology infrastructure quality significantly moderates the relationship between supplier integration and cost performance.
